Knowing how to set values to Silverlight objects can save you time when developing Silverlight applications. Silverlight is a Microsoft product used to build rich interaction applications for the Windows Phone, web and desktop using the .NET Framework. The .NET Framework is a class library made of classes, interfaces and value types required in Silverlight applications. You can create a simple Silverlight application and accomplish the task of setting a value to an object.
